After surviving 35 years, dozens of languages, hundreds of projects, thousands of meetings and millions of LOC, I now teach the basics to the computer-phobic

In software development, there are three kinds of problems: small, big and subtle. The small ones are usually fairly simple to track down; a misspelled label, a math error, etc. The large ones usually take longer to find; a race condition that you just can't reproduce, an external system randomly feeding you garbage, and so forth.

The subtle problems are an entirely different beast. It can be as simple as somebody entering 4321 instead of 432l (432L), or similar with 'i', 'l', '1', '0' and 'O'. It can be an interchanged comma and period. It can be something more complex, such as an unsupported third party library that throws back errors for undefined conditions, but randomly provides so little information as to be useful to neither user nor developer.

I Take Exception

We've all seen code that ignores errors. We've all seen code that simply rethrows an exception. We've all seen code that wraps one exception for another. The submitter, Mr. O, took exception to this exceptionally exceptional exception handling code.

I was particularly amused by the OutOfMemoryException handler that allocates another exception object, and if it fails, another layer of exception trapping catches that and attempts to allocate yet another exception object. if that fails, it doesn't even try. So that makes this an exceptionally unexceptional exception handler?! (ouch, my head hurts)

For Want of a CR…

A few years ago I was hired as an architect to help design some massive changes to a melange of existing systems so a northern foreign bank could meet some new regulatory requirements. As a development team, they gave me one junior developer with almost a year of experience. There were very few requirements and most of it would be guesswork to fill in the blanks. OK, typical Wall Street BS.

The junior developer was, well, junior, but bright, and he remembered what you taught him, so there was a chance we could succeed.
